The Sincaraz rivalry 2026

All of men’s tennis has come down to one big rivalry last year, Carlos Alcaraz against Jannik Sinner. Most experts and pundits expect this to continue into the 2026 season, with some challengers still struggling and their advantage seemingly just growing. But who might have the upper hand in the Sincaraz rivalry this year and what will the year end No. 1 race look like?

The Sinner-Alcaraz rivalry so far

The Sincaraz history has been an amazing one to witness so far. Where most of us were expecting a break from dominance after the Big Three, the two young guns obviously had other plans and took over seamlessly, only allowing a couple of major titles to slip to others before completely locking them down in 2024 and 2025. While Alcaraz had the faster breakout in 2022, Sinner’s rise was a bit more planned and step-by-step, but nonetheless impressive.

In the beginning of their encounters, it seemed as if Sinner would have the edge on hard court and that Alcaraz would benefit from the natural surfaces and their effect on the game. In 2024, he swept the titles in Paris and London, but severely struggled on hard courts, even before running into his rival sometimes. For that year, the Sincaraz rivalry was mostly in the rankings, where Sinner claimed the year-end No. 1 position after an impressive run throughout the US and Asian hard-court swing. The only three direct matchups went 3-0 in the favor of the Spaniard, including a five-set semifinal win in Roland Garros.

The 2025 season was expected to be another question of virtuosity versus consistency. This also showed in the Australian Open, where Alcaraz fell to the gamesmanship of Djokovic, while Sinner sailed to a dominant back-to-back title. After this, there was the doping ban of Jannik Sinner obviously, which prevented direct matches for months, before he returned in Rome. Alcaraz had not used his chances to win back the No. 1 spot in the rankings during that time but swept all relevant clay titles he competed for. He beat Sinner in Rome and of course won the epic Roland Garros final against him – a match that will most likely be replayed forever.

What happened next, was nothing short of surprises and turns of event. Sinner somehow figured out how to beat Alcaraz on grass, his maybe most dominant surface in the years before. Alcaraz went back to the drawing board and showed his best hard-court tennis afterwards, winning Cincinnati and the US Open in emphatic fashion. But the ultimate laugh was Sinner’s with a win at the ATP Finals, while Alcaraz walked away with the year-end No. 1.

The pre-season 2026

Of course, we have to talk about the Ferrero exit for the preseason. The announcement that the former No. 1 would no longer coach Alcaraz came nothing short of an explosion in the tennis news world. Experts have discussed at length if the split was for monetary, disciplinary or other reasons, but Carlos will be without Ferrero for the first time in his pro career. It seems to not bother him, as he won the Seoul exhibition and arrived very relaxed in Melbourne, but we have seen Ferrero’s coaching live a lot and it will have to be seen whether or which effect this has on his game.

Sinner on the other hand was able to convince Darren Cahill to stay with him for another year, forming the same team with Simone Vagnozzi going forward. This consistency might be beneficial for him in the rivalry, as he could continue with the things he had mentioned after losing to Alcaraz in New York. Sinner said that he wanted to get more multidimensional, including some variance into his game-style, as Alcaraz could always use these things to his advantage. On the other hand, Alcaraz will also stay with Samuel Lopez, who has been part of his team before. It remains unclear whether this will change his approach, but I would say that Sinner has had the slightly better offseason regarding preparation and coaching.

The race for No. 1 remains the overall target, with Alcaraz having the upper hand for now. The Spaniard can secure the spot with one win only in Melbourne, whereas Sinner must defend the title and 2000 points in the rankings. Afterwards, Sinner can gain quite some ground however, with him missing a couple of Masters events in 2025. So, if Alcaraz wants to get into Roland Garros the reigning No. 1, he will have to perform well throughout the clay season again. From Rome onwards, both players have a level playing field and will most likely be the only two competitors for this spot.

The 2026 prediction – 4 slams for (Sin)Alcaraz?

The other main target for these players will always be major titles. Currently the count is 5-3 in favor of Carlos Alcaraz, but Sinner will have the chance to get closer at his favorite Grand Slam so far. But will they only compete with each other for these titles? For the time being I do not see a clear-cut challenger to beat them on any surface. Alexander Zverev struggles with himself more than with Sincaraz in finals, Novak Djokovic turns 39 this year and will always have to prove his fitness first and all others, including Taylor Fritz and Lorenzo Musetti seem further away. Jack Draper seemed like a possible competitor but hasn’t played a competitive match in months, as has the other young gun, Arthur Fils.

Therefore, my prediction is another year with only two names in the winners’ column at major events, with the split still up for grabs. However, the 2025 US Open showed another level of Carlos Alcaraz, one that should scare Sinner fans. He was way more straight forward, less playful in a good way and a lot improved in his serving and returning. If the young Spaniard, who still might be one year behind in his development, can keep this trend and stay as cool-headed strategically, it will be hard to beat him anywhere.

My expectation is that the Australian Open will be a big deciding point for the season already. If Sinner cannot prevail there, he really has work to do, as even a not completely dialed-in Alcaraz beat him on clay repeatedly and will have a big advantage in the rankings, then. On the other hand, if Alcaraz reaches the final, it will already be a huge improvement from his 2025 Australian Open and he might be able to hit the ground running right away. I wouldn’t be surprised if 2026 becomes an Alcaraz show from the get-go, with three of four titles going his way, before running out of gas at the end. It might be too hard to attack Melbourne, play exhibitions, defend the clay swing and then stay consistent throughout the year at 22.

One thing I have learned though, is that you should rule out Sinner’s bounce back. He lost to Bublik in Halle last year and seemed to struggle hard on grass, before having the Wimbledon of his life. Granted, it seemed that Alcaraz was somehow off in the final and got stressed from consistently losing baseline battles – but Sinner amazed everyone with a top-notch performance. He remains the more consistent player, whereas Alcaraz most likely has the highest ceiling of any player on tour right now. And exactly this is what will decide their matchups in 2026, again – at least to my eyes. All other players will have to prove that they can be true challengers and stay physically and mentally healthy, first.
